Here are a few passages from the essay. I added the link to Wikipedia's article about the GRU, which the military/intel types who regularly read SST don't need explained:
Also relevant here is the fact that, rather transparently, this placing of the GRU centre stage is bound up with the attempt to suggest that there is some kind of ‘Gerasimov doctrine’, designed to undermine the West by ‘hybrid warfare.’
Unfortunately, the original author of this claptrap, Mark Galeotti, who, I regret to say, is, like Tait, British, has now recanted and confessed. In March, he published a piece on the ‘Foreign Policy’ site, under the title: ‘I’m Sorry for Creating the ‘Gerasimov Doctrine’; I was the first to write about Russia’s infamous high-tech military strategy. One small problem: it doesn't exist.’
(See https://foreignpolicy.com/2... .)
If anyone wants to grasp what the Chief of the General Staff of the Armed Forces of the Russian Federation, General Valery Gerasimov, was actually saying in the crucial February 2013 article which Galeotti was discussing, and how his thinking has developed subsequently, the place to look is, as so often, the Foreign Military Studies Office at Fort Leavenworth.

In relation to the ongoing attempt to frame the GRU, it is material that, in his 2013 piece, Gerasimov harks back to two pivotal figures in the arguments of the interwar years.
[...]David Habakkuk is British, thus his regret.
